Keysight Technologies FieldFox handheld signal analysers

Keysight Technologies has expanded the frequency range of its FieldFox handheld signal analysers, offering up to 170 GHz support for millimetre-wave (mmWave) signal analysis. Through a collaboration with Virginia Diodes Inc., Keysight’s A- and B-Series FieldFox handheld analysers with 18 GHz or higher can be paired with VDI PSAX frequency extenders to cover the sub-THz frequency range.

The handheld analysers enable mmWave measurements in a lightweight portable solution, when paired with VDI’s PSAX frequency extender modules. Engineers can also opt for the FieldFox equipped with the downloadable Option 357 pulse generator, which can be paired with a PSGX module from VDI, to also offer a mmWave signal generation solution up to 170 GHz. This enables users to obtain accurate mmWave measurements in an easy-to-use and rugged solution.

The handheld analysers also feature expanded frequency coverage, from as low as 18 GHz, depending on models, up to 170 GHz for either signal analysis or generation. The analysers also support in-band signal analysis with either spectrum analyser mode, IQ analyser mode or real-time spectrum analyser (RTSA) mode with a sensitivity of -155 dBm/Hz typical value.

Weighing approximately less than 4 kg in total, the combination of Keysight FieldFox and VDI frequency extenders makes the mmWave field testing more feasible and convenient for both field and lab environments.
